Roll forming, also spelled rollforming, is a continuous bending operation in which a long strip of sheet metal (typically coiled steel) is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.
Famous quotes containing the words roll and/or forming:
“It was easy to recognize in him the anti-social animus of a born evangelist, but there was also something else—a kind of voluptuous delight in the shabby and preposterous, a perverted aestheticism like that of a latter-day movie or radio fan, a wild will to roll in and snuffle balderdash as a cat rolls in and snuffles catnip.”
—H.L. (Henry Lewis)
“The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
